4. Package Contents
The package typically includes:
- Haozee MmWave Human Presence Sensor (Model ZY Wifi Wall Presence)
- USB Power Cable (for 5V1A power supply)
- Mounting Accessories (e.g., screws, adhesive tape for wall/ceiling mounting)
5. Setup
5.1 Powering the Device
Connect the provided USB cable to the sensor's USB port and plug the other end into a 5V1A USB power adapter (not always included). The sensor requires continuous power to operate.

5.2 Mounting
The sensor can be mounted on a wall or ceiling. Choose a location that provides an unobstructed view of the area you wish to monitor. Use the included mounting accessories to secure the sensor firmly.
5.3 App Integration and WiFi Connection
Download the recommended smart home application (e.g., Tuya Smart or Smart Life, as implied by product images) from your device's app store. Follow the in-app instructions to add the sensor and connect it to your 2.4GHz WiFi network. No additional hub is required for WiFi connectivity.
6. Operating Instructions
6.1 Basic Operation
Once powered and connected, the sensor will begin detecting human presence within its configured range. You can monitor its status and receive alerts through the mobile application.
6.2 Smart Scene Automation
Utilize the mobile application to create smart scenes. For example, you can configure the sensor to automatically turn on lights when presence is detected in a room and turn them off when no presence is detected for a set period.

7. Advanced Settings and Customization
7.1 Sensitivity Adjustment
Within the mobile application, you can adjust the sensor's sensitivity level, typically from 0 to 9, to fine-tune its detection capabilities for your specific environment.
7.2 Target Detection Distance
The app allows you to set and view the target detection distance, enabling you to define the precise area the sensor should monitor.
7.3 Illuminance Value
The sensor may provide an illuminance value, which can be used in advanced automation rules, for example, to only turn on lights if the ambient light level is below a certain threshold.
Figure 7.1: App interface for adjusting sensitivity, target distance, and viewing illuminance.
7.4 Minimum and Maximum Detection Distance
You can configure the minimum and maximum detection distances to create a specific alarm zone, optimizing the sensor's performance for your space.

8. Maintenance
To ensure optimal performance, keep the sensor clean and free from dust. Use a soft, dry cloth for cleaning. Avoid using abrasive cleaners or solvents. Ensure the sensor's detection area remains unobstructed.
9. Troubleshooting
- False Alarms or Missed Detections: Adjust the sensitivity settings in the app. Ensure the sensor is mounted correctly and its field of view is clear. Consider adjusting the minimum and maximum detection distances.
- Connectivity Issues: Verify that the sensor is within range of your 2.4GHz WiFi network. Restart the sensor and your WiFi router. Ensure the app is updated to the latest version.
- Reducing False Alarms: To minimize false alarms and improve integration with other sensors, you can configure the interval time for alternating between 'human detected' and 'no one' statuses within the application.
- Sensor Not Powering On: Check the USB cable connection and ensure the 5V1A power adapter is functioning correctly.
